Our take on Moon Observatory Iris
Players looking for systems beyond visual-novel reading may bounce off when they discover that the game keeps its interaction to story choices. Those seeking route discovery may also stop at the first clearly signposted ending decision.
What is Moon Observatory Iris?
Moon Observatory Iris is an otome visual novel centered on Iris, a Purifier who guides the souls of the dead beyond the mortal world.
Her life takes a different course when she meets the Magicians, beings with half-immortal lives who guard the MO worlds. Through their encounters, the history behind those worlds comes into view. The fantasy narrative mixes jokes and playful moments with blood, death themes, and more serious developments. Its cast includes Iris, her childhood friend Rieffe, her past teacher Reqieu, and the Magicians Lanneis and Septem.
Player choices can change the ending. After one playthrough, an Extras section provides guidance for reaching the Good and Bad Ends. The story is self-contained, with references to Ciel and Anholly; bonus routes are added free when purchase milestones are reached.
